Making dynamic text boxes only display full words?

Is it possible to make dynamic text boxes display only full words from an xml feed? At the moment I have a selection of feeds that are supposed to run into each other, but if some of the text is longer than expected I get the first one or two characters of a word tagged on at the end. Is it possible to have the flash read whether it has character space left to display the next word in the xml?

I know it doesn’t really recognise spaces etc and just pulls in the info within the node, but maybe there’s a work-around if you want to do what I’m trying?
